Re: [PATCH 00/25] Exynos DRM: new life of IPP (Image Post Processing) subsystem

Hello Marek, this looks very interesting. I'll try to integrate this with my mpv DRM backend once the colorspace conversion bits are implemented. I also wanted to suggest that using the IPP blocks (rotator, FIMC) should be still be possible without any kind of display active. So similar in the
